JSmooth .exe wrapper
JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your Java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a website.
JSmooth provides a variety of wrappers for your java application, each of them having their own behavior: Choose your flavor!

JarToExe 1.8 Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe on their website:
Can generate “Console”, “Windows GUI”, “Windows Service” three types of .exe files.
Generated .exe files can add program icons and version information. Generated .exe files can encrypt and protect java programs, no temporary files will be generated when the program runs.
Generated .exe files provide system tray icon support. Generated .exe files provide record system event log support. Generated windows service .exe files are able to install/uninstall itself, and support service pause/continue.
Executor
Package your Java application as a jar, and Executor will turn the jar into a Windows .exe file, indistinguishable from a native application. Simply double-clicking the .exe file will invoke the Java Runtime Environment and launch your application.
You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.
I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).
To install it, you can either download it from the linked website or use the command:
pip install pyinstaller
...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:
pyinstaller myscript.py
You can find more information about how to use Pyinstaller and customize the build process via the documentation.
You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.
All executable files from Visual Studio should be located in the debug folder of your project, e.g:
Visual Studio Directory: c:\users\me\documents\visual studio
Then the project which was called 'hello world' would be in the directory:
c:\users\me\documents\visual studio\hello world
And your exe would be located in:
c:\users\me\documents\visual studio\hello world\Debug\hello world.exe
Note the exe being named the same as the project.
Otherwise, you could publish it to a specified folder of your choice which comes with an installation, which would be good if you wanted to distribute it quickly
EDIT:
Everytime you build your project in VS, the exe is updated with the new one according to the code (as long as it builds without errors). When you publish it, you can choose the location, aswell as other factors, and the setup exe will be in that location, aswell as some manifest files and other files about the project.
Quick Answer:
foreach (var process in Process.GetProcessesByName("whatever"))
{
process.Kill();
}
(leave off .exe from process name)
Steps to convert .py to .exe in Python 3.6
pip install cx_Freeze
.pip install idna
..py
program named myfirstprog.py
.setup.py
on the current directory of your script.setup.py
file, copy the code below and save it.python setup.py build
build
. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.See the original script in my blog.
setup.py:
from cx_Freeze import setup, Executable
base = None
executables = [Executable("myfirstprog.py", base=base)]
packages = ["idna"]
options = {
'build_exe': {
'packages':packages,
},
}
setup(
name = "<any name>",
options = options,
version = "<any number>",
description = '<any description>',
executables = executables
)
EDIT:
myfirstprog.py
you should put your .py
extension file name as created in step 4;import
ed package in your .py
into packages
list (ex: packages = ["idna", "os","sys"]
)any name, any number, any description
in setup.py
file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = ''
)import
ed packages must be installed before you start step 8.You're on the right track. The two constructors accept arguments, or you can specify them post-construction with ProcessBuilder#command(java.util.List)
and ProcessBuilder#command(String...)
.
I notice that all the prior answers use older Win32 User library functions to accomplish this. I think this will work in most cases, but will work less reliably over time.
Now, not having done this, I can't tell you how well it will work, but I do know that a current Windows technology might be a better solution: the Desktop Windows Manager API.
DWM is the same technology that lets you see live thumbnail previews of apps using the taskbar and task switcher UI. I believe it is closely related to Remote Terminal services.
I think that a probable problem that might happen when you force an app to be a child of a parent window that is not the desktop window is that some application developers will make assumptions about the device context (DC), pointer (mouse) position, screen widths, etc., which may cause erratic or problematic behavior when it is "embedded" in the main window.
I suspect that you can largely eliminate these problems by relying on DWM to help you manage the translations necessary to have an application's windows reliably be presented and interacted with inside another application's container window.
The documentation assumes C++ programming, but I found one person who has produced what he claims is an open source C# wrapper library: https://bytes.com/topic/c-sharp/answers/823547-desktop-window-manager-wrapper. The post is old, and the source is not on a big repository like GitHub, bitbucket, or sourceforge, so I don't know how current it is.
Go to file->export->JAR file, there you may select "Export generated class files and sources" and make sure that your project is selected, and all folder under there are also! Good luck!
You need to add C:\xampp\php
to your PATH Environment Variable
, Only after then you would be able to execute php
command line from outside php_home
.
Alternatively, you can use some java-to-c translator (e.g., JCGO) and compile the generated C files to a native binary (.exe) file for the target platform.
Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.
AFAIK, these are your options:
Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters
There also executable wrappers - see How can I convert my Java program to an .exe file?
I found this presentation to be very helpfull.
How I Distribute Python applications on Windows - py2exe & InnoSetup
From the site:
There are many deployment options for Python code. I'll share what has worked well for me on Windows, packaging command line tools and services using py2exe and InnoSetup. I'll demonstrate a simple build script which creates windows binaries and an InnoSetup installer in one step. In addition, I'll go over common errors which come up when using py2exe and hints on troubleshooting them. This is a short talk, so there will be a follow-up Open Space session to share experience and help each other solve distribution problems.
When executable path has whitespace in system, call
#include<iostream>
using namespace std;
int main()
{
system("explorer C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe ");
system("pause");
return 0;
}
Another option, if you need to sign the executable on a Linux box is to use signcode from the Mono project tools. It is supported on Ubuntu.
If you really want an exe Excelsior JET is a professional level product that compiles to native code:
http://www.excelsior-usa.com/jet.html
You can also look at JSMooth:
http://jsmooth.sourceforge.net/
And if your application is compatible with its compatible with AWT/Apache classpath then GCJ compiles to native exe.
There is another way to convert Python scripts to .exe files. You can compile Python programs into C++ programs, which can be natively compiled just like any other C++ program.
The .exe is the program. The .dll is a library that a .exe (or another .dll) may call into.
What sakthivignesh says can be true in that one .exe can use another as if it were a library, and this is done (for example) with some COM components. In this case, the "slave" .exe is a separate program (strictly speaking, a separate process - perhaps running on a separate machine), but one that accepts and handles requests from other programs/components/whatever.
However, if you just pick a random .exe and .dll from a folder in your Program Files, odds are that COM isn't relevant - they are just a program and its dynamically-linked libraries.
Using Win32 APIs, a program can load and use a DLL using the LoadLibrary and GetProcAddress API functions, IIRC. There were similar functions in Win16.
COM is in many ways an evolution of the DLL idea, originally concieved as the basis for OLE2, whereas .NET is the descendant of COM. DLLs have been around since Windows 1, IIRC. They were originally a way of sharing binary code (particularly system APIs) between multiple running programs in order to minimise memory use.
Cmd can handle running a quoted exe, but Powershell can't. I'm just going to deal with running the exe itself, since I don't have it. If you literally need to send doublequotes to an argument of an external command, that's another issue that's been covered elsewhere.
1) add the exe folder to your path, maybe in your $profile
$env:path += ';C:\Program Files\IIS\Microsoft Web Deploy\'
msdeploy
2) backquote the spaces:
C:\Program` Files\IIS\Microsoft` Web` Deploy\msdeploy.exe
There is Resource Tuner Console from Heaventools Software.
Resource Tuner Console is a command-line tool that enables developers to automate editing of different resource types in large numbers of Windows 32- and 64-bit executable files.
See specifically the Changing Version Variables And Updating The Version Information page for greater details.
I did find any of these solutions met my requirements, so made my own version of node called node2exe that does this. It's available from https://github.com/areve/node2exe
If your folders are set to "hide file extensions", you'll name the file *.bat or *.cmd and it will still be a text file (hidden .txt extension). Be sure you can properly name a file!
I would like to suggest additional solution to fix this issue. So, I recommend to reinstall/install the latest Windows SDK
. In my case it has helped me to fix the issue when using Qt
with MSVC
compiler to debug a program.
You can compile with either Cygwin's g++
or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll
(and others) PATH to the system Windows PATH, before any cygwin style paths.
Thus add: ;C:\cygwin64\bin
to the end of your Windows system PATH
variable.
Also, to compile for use in CMD or PowerShell, you may need to use:
x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe
(This invokes the cross-compiler, if installed.)
The easiest way would be to use use ProcessExplorer but it would still require some searching.
Make sure your exe is running and open ProcessExplorer. In ProcessExplorer find the name of your binary file and double click it to show properties. Click the Strings tab. Search down the list of string found in the binary file. Most strings will be garbage so they can be ignored. Search for anything that might possibly resemble a command line switch. Test this switch from the command line and see if it does anything.
Note that it might be your binary simply has no command line switches.
For reference here is the above steps applied to the Chrome executable. The command line switches accepted by Chrome can be seen in the list:
From this post:
To get the entire PC CPU and Memory usage:
using System.Diagnostics;
Then declare globally:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Processor", "% Processor Time", "_Total");
Then to get the CPU time, simply call the NextValue()
method:
this.theCPUCounter.NextValue();
This will get you the CPU usage
As for memory usage, same thing applies I believe:
private PerformanceCounter theMemCounter =
new PerformanceCounter("Memory", "Available MBytes");
Then to get the memory usage, simply call the NextValue()
method:
this.theMemCounter.NextValue();
For a specific process CPU and Memory usage:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Process", "% Processor Time",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
private PerformanceCounter theMemCounter =
new PerformanceCounter("Process", "Working Set",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?
To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters
The difference between Processor\% Processor Time
and Process\% Processor Time
is Processor
is from the PC itself and Process
is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters
An alternative to using the Performance Counter
Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.
Features of C# Absent in Java • C# includes more primitive types and the functionality to catch arithmetic exceptions.
• Includes a large number of notational conveniences over Java, many of which, such as operator overloading and user-defined casts, are already familiar to the large community of C++ programmers.
• Event handling is a "first class citizen"—it is part of the language itself.
• Allows the definition of "structs", which are similar to classes but may be allocated on the stack (unlike instances of classes in C# and Java).
• C# implements properties as part of the language syntax.
• C# allows switch statements to operate on strings.
• C# allows anonymous methods providing closure functionality.
• C# allows iterator that employs co-routines via a functional-style yield keyword.
• C# has support for output parameters, aiding in the return of multiple values, a feature shared by C++ and SQL.
• C# has the ability to alias namespaces.
• C# has "Explicit Member Implementation" which allows a class to specifically implement methods of an interface, separate from its own class methods. This allows it also to implement two different interfaces which happen to have a method of the same name. The methods of an interface do not need to be public; they can be made to be accessible only via that interface.
• C# provides integration with COM.
• Following the example of C and C++, C# allows call by reference for primitive and reference types.
Features of Java Absent in C#
• Java's strictfp keyword guarantees that the result of floating point operations remain the same across platforms.
• Java supports checked exceptions for better enforcement of error trapping and handling.
An example on how to use that would be great. There is a couple of examples at the Qt forum, but you're right that the official documentation should be expanded.
QJsonDocument
on its own indeed doesn't produce anything, you will have to add the data to it. That's done through the QJsonObject
, QJsonArray
and QJsonValue
classes. The top-level item needs to be either an array or an object (because 1
is not a valid json document, while {foo: 1}
is.)
For my this is best solution.
function strip_tags_content($string) {
// ----- remove HTML TAGs -----
$string = preg_replace ('/<[^>]*>/', ' ', $string);
// ----- remove control characters -----
$string = str_replace("\r", '', $string);
$string = str_replace("\n", ' ', $string);
$string = str_replace("\t", ' ', $string);
// ----- remove multiple spaces -----
$string = trim(preg_replace('/ {2,}/', ' ', $string));
return $string;
}
You can't directly manipulate a session value from Javascript - they only exist on the server.
You could let your Javascript get and set values in the session by using AJAX calls though.

Explanation of command that i am going to write:-
.
means any character, digit can come in place of .
*
means zero or more occurrences of thing written just previous to it.
|
means 'or'.
So,
james.*jack
would search james
, then any number of character until jack
comes.
Since you want either jack.*james
or james.*jack
Hence Command:
jack.*james|james.*jack
I know the original posters question was solved, but I came here via Google, and the various answers eventually led me to discovering that my SQL was dumped with a different default charset than the one used to import it. I got the same error as the original question, but as our dump was piped into another MySQL client, we couldn't go the route of opening it with another tool and saving it differently.
For us, the solution turned out to be the --default-character-set=utf8mb4
option, to be used both on the call of mysqldump
as well as the call to import it via mysql
. Of course, the value of the parameter may differ for others facing the same problem, it's just important to keep it the same, as the servers (or the tools) default setting might be any charset.
Bootstrapping has yet another meaning in the context of reinforcement learning that may be useful to know for developers, in addition to its use in software development (most answers here, e.g. by kdgregory) and its use in statistics as discussed by Dirk Eddelbuettel.
From Sutton and Barto:
Widrow, Gupta, and Maitra (1973) modified the Least-Mean-Square (LMS) algorithm of Widrow and Hoff (1960) to produce a reinforcement learning rule that could learn from success and failure signals instead of from training examples. They called this form of learning “selective bootstrap adaptation” and described it as “learning with a critic” instead of “learning with a teacher.” They analyzed this rule and showed how it could learn to play blackjack. This was an isolated foray into reinforcement learning by Widrow, whose contributions to supervised learning were much more influential.
The book describes various reinforcement algorithms where the target value is based on a previous approximation as bootstrap methods:
Finally, we note one last special property of DP [Dynamic Programming] methods. All of them update estimates of the values of states based on estimates of the values of successor states. That is, they update estimates on the basis of other estimates. We call this general idea bootstrapping. Many reinforcement learning methods perform bootstrapping, even those that do not require, as DP requires, a complete and accurate model of the environment.
Note that this differs from bootstrap aggregating and intelligence explosion that is mentioned on the wikipedia page on bootstrapping.

@vimal answer did not provide solution for me. It seems the orientation is not the current orientation, but from previous orientation. To fix it, I use [[UIDevice currentDevice] orientation]
- (void)orientationChanged:(NSNotification *)notification{
[self adjustViewsForOrientation:[[UIDevice currentDevice] orientation]];
}
Then
- (void) adjustViewsForOrientation:(UIDeviceOrientation) orientation { ... }
With this code I get the current orientation position.
Quick note: Check if you have other Python versions, if you have removed them, make sure you did that right. If you have Miniconda on your system then Python will not be removed easily.
What worked for me: removed other Python versions and the Miniconda, reinstalled Python and the matplotlib library and everything worked great.
In Bootstrap 4 you can use the form-check-inline class.
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="queryFieldName" id="option1" value="1">
<label class="form-check-label" for="option1">First</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="queryFieldName" id="option2" value="2">
<label class="form-check-label" for="option2">Second</label>
</div>
IMHO, the most elegant way is using the Java API for JSON Processing (JSON-P), one of the JavaEE standards that conforms to the JSR 374.
try(StringReader sr = new StringReader(jsonStrn)) {
Json.createReader(sr).readObject();
} catch(JsonParsingException e) {
System.out.println("The given string is not a valid json");
e.printStackTrace();
}
Using Maven, add the dependency on JSON-P:
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.json</artifactId>
<version>1.1.4</version>
</dependency>
Visit the JSON-P official page for more informations.
A polyfill is a piece of code (or plugin) that provides the technology that you, the developer, expect the browser to provide natively.
The accepted answer by dr jimbob (using make altinstall
) got me most of the way there, with python2.7
in /usr/local/bin
but I also needed to install some third party modules. The nice thing is that easy_install gets its installation locations from the version of Python you are running, but I found I still needed to install easy_install for Python 2.7 otherwise I would get ImportError: No module named pkg_resources
. So I did this:
wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
sudo -i
export PATH=$PATH:/usr/local/bin
sh setuptools-0.6c11-py2.7.egg
exit
Now I have easy_install
and easy_install-2.7
in /usr/local/bin and the former overrides my system's 2.6 version of easy_install, so I removed it:
sudo rm /usr/local/bin/easy_install
Now I can install libraries for the 2.7 version of Python like this:
sudo /usr/local/bin/easy_install-2.7 numpy
I found this worked best for me.
In AndroidManifest.xml <activity> element
add android:windowSoftInputMode="stateHidden"
This always hides the keyboard when entering the activity.
It appears you could use a list
instead of a tuple
.
This becomes more important I think when you are grabbing attributes instead of 'magic indexes' of a list/tuple.
In my case I wanted to sort by multiple attributes of a class, where the incoming keys were strings. I needed different sorting in different places, and I wanted a common default sort for the parent class that clients were interacting with; only having to override the 'sorting keys' when I really 'needed to', but also in a way that I could store them as lists that the class could share
So first I defined a helper method
def attr_sort(self, attrs=['someAttributeString']:
'''helper to sort by the attributes named by strings of attrs in order'''
return lambda k: [ getattr(k, attr) for attr in attrs ]
then to use it
# would defined elsewhere but showing here for consiseness
self.SortListA = ['attrA', 'attrB']
self.SortListB = ['attrC', 'attrA']
records = .... #list of my objects to sort
records.sort(key=self.attr_sort(attrs=self.SortListA))
# perhaps later nearby or in another function
more_records = .... #another list
more_records.sort(key=self.attr_sort(attrs=self.SortListB))
This will use the generated lambda function sort the list by object.attrA
and then object.attrB
assuming object
has a getter corresponding to the string names provided. And the second case would sort by object.attrC
then object.attrA
.
This also allows you to potentially expose outward sorting choices to be shared alike by a consumer, a unit test, or for them to perhaps tell you how they want sorting done for some operation in your api by only have to give you a list and not coupling them to your back end implementation.

You can tell Acrobat Reader to print the file using (as someone's already mentioned here) the 'print' verb. You will need to close Acrobat Reader programmatically after that, too:
private void SendToPrinter()
{
ProcessStartInfo info = new ProcessStartInfo();
info.Verb = "print";
info.FileName = @"c:\output.pdf";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process p = new Process();
p.StartInfo = info;
p.Start();
p.WaitForInputIdle();
System.Threading.Thread.Sleep(3000);
if (false == p.CloseMainWindow())
p.Kill();
}
This opens Acrobat Reader and tells it to send the PDF to the default printer, and then shuts down Acrobat after three seconds.
If you are willing to ship other products with your application then you could use GhostScript (free), or a command-line PDF printer such as http://www.commandlinepdf.com/ (commercial).
Note: the sample code opens the PDF in the application current registered to print PDFs, which is the Adobe Acrobat Reader on most people's machines. However, it is possible that they use a different PDF viewer such as Foxit (http://www.foxitsoftware.com/pdf/reader/). The sample code should still work, though.
You might need to allow different combinations of data in your intent filter to get it to work in different cases (http/
vs https/
, www.
vs no www.
, etc).
For example, I had to do the following for an app which would open when the user opened a link to Google Drive forms (www.docs.google.com/forms
)
Note that path prefix is optional.
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="www.docs.google.com" />
<data android:host="docs.google.com" />
<data android:pathPrefix="/forms" />
</intent-filter>
If you don't want to use a List
, ArrayList
, or other dynamically-sized collection and then convert to an array (that's the method I'd recommend, by the way), then you'll have to allocate the array to its maximum possible size, keep track of how many items you put in it, and then create a new array with just those items in it:
private Update BuildMetaData(MetaData[] nvPairs)
{
Update update = new Update();
InputProperty[] ip = new InputProperty[20]; // how to make this "dynamic"
int i;
for (i = 0; i < nvPairs.Length; i++)
{
if (nvPairs[i] == null) break;
ip[i] = new InputProperty();
ip[i].Name = "udf:" + nvPairs[i].Name;
ip[i].Val = nvPairs[i].Value;
}
if (i < nvPairs.Length)
{
// Create new, smaller, array to hold the items we processed.
update.Items = new InputProperty[i];
Array.Copy(ip, update.Items, i);
}
else
{
update.Items = ip;
}
return update;
}
An alternate method would be to always assign update.Items = ip;
and then resize if necessary:
update.Items = ip;
if (i < nvPairs.Length)
{
Array.Resize(update.Items, i);
}
It's less code, but will likely end up doing the same amount of work (i.e. creating a new array and copying the old items).
If you don't care about supporting old browsers, you can use :not()
to exclude that element:
.parent:hover span:not(:hover) {
border: 10px solid red;
}
Demo: http://jsfiddle.net/vz9A9/1/
If you do want to support them, the I guess you'll have to either use JavaScript or override the CSS properties again:
.parent span:hover {
border: 10px solid green;
}
Check on your index.php
, find "... charset=iso-8859-1
" and replace it with "... charset=utf-8
".
Maybe it'll work.
x = x + 1 print(x) a = x + 5 print(a)
SQL JOIN
?SQL JOIN
is a method to retrieve data from two or more database tables.
SQL JOIN
s ?There are a total of five JOIN
s. They are :
1. JOIN or INNER JOIN
2. OUTER JOIN
2.1 LEFT OUTER JOIN or LEFT JOIN
2.2 RIGHT OUTER JOIN or RIGHT JOIN
2.3 FULL OUTER JOIN or FULL JOIN
3. NATURAL JOIN
4. CROSS JOIN
5. SELF JOIN
In this kind of a JOIN
, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.
In other words, INNER JOIN
is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.
Note that a JOIN
without any other JOIN
keywords (like INNER
, OUTER
, LEFT
, etc) is an INNER JOIN
. In other words, JOIN
is
a Syntactic sugar for INNER JOIN
(see: Difference between JOIN and INNER JOIN).
OUTER JOIN
retrieves
Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).
There are three kinds of Outer Join :
2.1 LEFT OUTER JOIN or LEFT JOIN
This join returns all the rows from the left table in conjunction with the matching rows from the
right table. If there are no columns matching in the right table, it returns NULL
values.
2.2 RIGHT OUTER JOIN or RIGHT JOIN
This JOIN
returns all the rows from the right table in conjunction with the matching rows from the
left table. If there are no columns matching in the left table, it returns NULL
values.
2.3 FULL OUTER JOIN or FULL JOIN
This JOIN
combines LEFT OUTER JOIN
and RIGHT OUTER JOIN
. It returns rows from either table when the conditions are met and returns NULL
value when there is no match.
In other words, OUTER JOIN
is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.
Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.
It is based on the two conditions :
JOIN
is made on all the columns with the same name for equality.This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.
It is the Cartesian product of the two tables involved. The result of a CROSS JOIN
will not make sense
in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).
It is not a different form of JOIN
, rather it is a JOIN
(INNER
, OUTER
, etc) of a table to itself.
Depending on the operator used for a JOIN
clause, there can be two types of JOIN
s. They are
For whatever JOIN
type (INNER
, OUTER
, etc), if we use ONLY the equality operator (=), then we say that
the JOIN
is an EQUI JOIN
.
This is same as EQUI JOIN
but it allows all other operators like >, <, >= etc.
Many consider both
EQUI JOIN
and ThetaJOIN
similar toINNER
,OUTER
etcJOIN
s. But I strongly believe that its a mistake and makes the ideas vague. BecauseINNER JOIN
,OUTER JOIN
etc are all connected with the tables and their data whereasEQUI JOIN
andTHETA JOIN
are only connected with the operators we use in the former.Again, there are many who consider
NATURAL JOIN
as some sort of "peculiar"EQUI JOIN
. In fact, it is true, because of the first condition I mentioned forNATURAL JOIN
. However, we don't have to restrict that simply toNATURAL JOIN
s alone.INNER JOIN
s,OUTER JOIN
s etc could be anEQUI JOIN
too.
whenever i try to compile the code it says "{"Input string was not in a correct format."}"
This error won't come on compiling.
Now the error comese because you are trying to parse an invalid string to integer. To do it in a safe manner, you should do it like this
int questionID;
if(int.TryParse(vTwoOrMoreOptions.SelectedItems[0].Text.ToString(),out questionID))
{
//success code
}
else
{
//failure code
}
You can use
ng-bind-html https://docs.angularjs.org/api/ng/service/$sce
directive to bind html dynamically. However you have to get the data via $sce service.
Please see the live demo at http://plnkr.co/edit/k4s3Bx
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
$scope.getHtml=function(){
return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
}
});
<body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
</body>
Perform a hard reboot of your phone. The easiest way to do this is to remove the phone's battery. Wait for at least 30 seconds, then replace the battery. The phone will reboot, and upon completing its restart will have an empty DNS cache.
Read more: How to Flush the DNS on an Android Phone | eHow.com http://www.ehow.com/how_10021288_flush-dns-android-phone.html#ixzz1gRJnmiJb
The better pattern is to create a standalone BroadcastReceiver
. This insures that your app can respond to the broadcast, whether or not the Service
is running. In fact, using this pattern may remove the need for a constant-running Service
altogether.
Register the BroadcastReceiver
in your Manifest, and create a separate class/file for it.
Eg:
<receiver android:name=".FooReceiver" >
<intent-filter >
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
When the receiver runs, you simply pass an Intent
(Bundle
) to the Service
, and respond to it in onStartCommand()
.
Eg:
public class FooReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// do your work quickly!
// then call context.startService();
}
}
It always bothered me that I can't use the String.Remove
method to get rid of instances of a string or character in a string so I usually add theses extension methods to my code base:
public static class StringExtensions
{
public static string Remove(this string str, string toBeRemoved)
{
return str.Replace(toBeRemoved, "");
}
public static string RemoveChar(this string str, char toBeRemoved)
{
return str.Replace(toBeRemoved.ToString(), "");
}
}
The one taking char
can't use overload semantics unfortunately since it will resolve to string.Remove(int startIndex)
since it is "closer"
This is of course purely esthetics, but I like it...
Making changes as below and redeploying on server content type as
Response.ContentType = "application/octet-stream";
This worked for me.
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.WriteFile(file.FullName);
Response.End();
For anyone that searched and pressed on this link, i solved it by simply searching for mysql notifier and stop mysql from running there, Then run mysql in xampp again and it runs. why this works ? iam not expert, but i think it is easy : port was taken already by mysql notifier so had to stop it there and run it here.
Spring provides two kinds of IOC container, one is
XMLBeanFactory
and other isApplicationContext
.
+---------------------------------------+-----------------+--------------------------------+
| | BeanFactory | ApplicationContext |
+---------------------------------------+-----------------+--------------------------------+
| Annotation support | No | Yes |
| BeanPostProcessor Registration | Manual | Automatic |
| implementation | XMLBeanFactory | ClassPath/FileSystem/WebXmlApplicationContext|
| internationalization | No | Yes |
| Enterprise services | No | Yes |
| ApplicationEvent publication | No | Yes |
+---------------------------------------+-----------------+--------------------------------+
FileSystemXmlApplicationContext
Beans loaded through the full path.ClassPathXmlApplicationContext
Beans loaded through the CLASSPATHXMLWebApplicationContext
and AnnotationConfigWebApplicationContext
beans loaded through the web application context.AnnotationConfigApplicationContext
Loading Spring beans from Annotation based configuration. example:
ApplicationContext applicationContext = new AnnotationConfigApplicationContext(BeansConfiguration.class);
ApplicationContext
is the container initialized by a ContextLoaderListener
or ContextLoaderServlet
defined in a web.xml
and ContextLoaderPlugin
defined in struts-config.xml
.Note: XmlBeanFactory
is deprecated as of Spring 3.1 in favor of DefaultListableBeanFactory
and XmlBeanDefinitionReader
.
username = 'MICHAEL89'
if username.upper() in (name.upper() for name in USERNAMES):
...
Alternatively:
if username.upper() in map(str.upper, USERNAMES):
...
Or, yes, you can make a custom method.
What kind of authentication are you using? If it's Forms authentication, then at best, you'll have to find the .ASPXAUTH cookie and pass it in the WebClient
request.
At worst, it won't work.
You can use GROUP BY SalesOrderID
. The difference is, with GROUP BY you can only have the aggregated values for the columns that are not included in GROUP BY.
In contrast, using windowed aggregate functions instead of GROUP BY, you can retrieve both aggregated and non-aggregated values. That is, although you are not doing that in your example query, you could retrieve both individual OrderQty
values and their sums, counts, averages etc. over groups of same SalesOrderID
s.
Here's a practical example of why windowed aggregates are great. Suppose you need to calculate what percent of a total every value is. Without windowed aggregates you'd have to first derive a list of aggregated values and then join it back to the original rowset, i.e. like this:
SELECT
orig.[Partition],
orig.Value,
orig.Value * 100.0 / agg.TotalValue AS ValuePercent
FROM OriginalRowset orig
INNER JOIN (
SELECT
[Partition],
SUM(Value) AS TotalValue
FROM OriginalRowset
GROUP BY [Partition]
) agg ON orig.[Partition] = agg.[Partition]
Now look how you can do the same with a windowed aggregate:
SELECT
[Partition],
Value,
Value * 100.0 / SUM(Value) OVER (PARTITION BY [Partition]) AS ValuePercent
FROM OriginalRowset orig
Much easier and cleaner, isn't it?
The Oj gem (https://github.com/ohler55/oj) should work. It's simple and fast.
http://www.ohler.com/oj/#Simple_JSON_Writing_and_Parsing_Example
require 'oj'
h = { 'one' => 1, 'array' => [ true, false ] }
json = Oj.dump(h)
# json =
# {
# "one":1,
# "array":[
# true,
# false
# ]
# }
h2 = Oj.load(json)
puts "Same? #{h == h2}"
# true
The Oj gem won't work for JRuby. For JRuby this (https://github.com/ralfstx/minimal-json) or this (https://github.com/clojure/data.json) may be good options.
For the record, the spring.jpa.hibernate.ddl-auto
property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto
.
The values create
, create-drop
, validate
, and update
basically influence how the schema tool management will manipulate the database schema at startup.
For example, the update
operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.
The update
operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.
Typically in test case scenarios, you'll likely use create-drop
so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.
In development, it's often common to see developers use update
to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.
In production, it's often highly recommended you use none
or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.
You can use DISTINCT
like that
mysql_query("SELECT DISTINCT(ticket_id), column1, column2, column3
FROM temp_tickets
ORDER BY ticket_id");
So, static methods are the methods which can be called without creating the object of a class. For Example :-
@staticmethod
def add(a, b):
return a + b
b = A.add(12,12)
print b
In the above example method add
is called by the class name A
not the object name.
If you want to checkout all the files 'anywhere'
git checkout -- $(git rev-parse --show-toplevel)
Only @Component
can be a node in the change detection tree. This means that you cannot set ChangeDetectionStrategy.OnPush
in a @Directive
. Despite this fact, a Directive can have @Input
and @Output
properties and you can inject and manipulate host component's ChangeDetectorRef
from it. So use Components when you need a granular control over your change detection tree.
^\d\d?[,.]\d\d?$
The ^ and $ means begin and end of input string (without this part 23.45 of string like 123.45 will be matched). The \d means digit, the \d? means optional digit, the [,.] means dot or comma. Working example (when you click on left menu> tools> code generator you can gen code for one of 9 popular languages like c#, js, php, java, ...) here.
// TEST

I'm not sure what you're trying to do: If you added the file via
svn add myfile
you only told svn to put this file into your repository when you do your next commit. There's no change to the repository before you type an
svn commit
If you delete the file before the commit, svn
has it in its records (because you added it) but cannot send it to the repository because the file no longer exist.
So either you want to save the file in the repository and then delete it from your working copy: In this case try to get your file back (from the trash?), do the commit and delete the file afterwards via
svn delete myfile
svn commit
If you want to undo the add
and just throw the file away, you can to an
svn revert myfile
which tells svn
(in this case) to undo the add-Operation.
EDIT
Sorry, I wasn't aware that you're using the "Versions" GUI client for Max OSX. So either try a revert on the containing directory using the GUI or jump into the cold water and fire up your hidden Mac command shell :-) (it's called "Terminal" in the german OSX, no idea how to bring it up in the english version...)
Add this in the head section of your html
<link rel="icon" type="image/gif/png" href="mouse_select_left.png">
This is probably the easiest way, not the prettiest though:
SELECT *,
(SELECT Count(*) FROM eventsTable WHERE columnName = 'Business') as RowCount
FROM eventsTable
WHERE columnName = 'Business'
This will also work without having to use a group by
SELECT *, COUNT(*) OVER () as RowCount
FROM eventsTables
WHERE columnName = 'Business'
Here is Apple's documentation:
It says there are two things that you must get right:

.If this still doesn't help you, double check that you are really changing the architecture build settings for the right build configuration – I wasted half an hour fiddling with the wrong one and wondering why it didn't work...
Select Edit Scheme...
in the Product menu, click the "Archive" scheme in the left list and check the Build Configuration. Change the value if it was not what you expected.
Old question, but the autolayout-solution with runtime border adjustments still missing.
borders(for: [.left, .bottom], width: 2, color: .red)
The following UIView extension will add the border only on the given edges. If you change the edges at runtime, the borders will adjust accordingly.
extension UIView {
func borders(for edges:[UIRectEdge], width:CGFloat = 1, color: UIColor = .black) {
if edges.contains(.all) {
layer.borderWidth = width
layer.borderColor = color.cgColor
} else {
let allSpecificBorders:[UIRectEdge] = [.top, .bottom, .left, .right]
for edge in allSpecificBorders {
if let v = viewWithTag(Int(edge.rawValue)) {
v.removeFromSuperview()
}
if edges.contains(edge) {
let v = UIView()
v.tag = Int(edge.rawValue)
v.backgroundColor = color
v.translatesAutoresizingMaskIntoConstraints = false
addSubview(v)
var horizontalVisualFormat = "H:"
var verticalVisualFormat = "V:"
switch edge {
case UIRectEdge.bottom:
horizontalVisualFormat += "|-(0)-[v]-(0)-|"
verticalVisualFormat += "[v(\(width))]-(0)-|"
case UIRectEdge.top:
horizontalVisualFormat += "|-(0)-[v]-(0)-|"
verticalVisualFormat += "|-(0)-[v(\(width))]"
case UIRectEdge.left:
horizontalVisualFormat += "|-(0)-[v(\(width))]"
verticalVisualFormat += "|-(0)-[v]-(0)-|"
case UIRectEdge.right:
horizontalVisualFormat += "[v(\(width))]-(0)-|"
verticalVisualFormat += "|-(0)-[v]-(0)-|"
default:
break
}
self.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: horizontalVisualFormat, options: .directionLeadingToTrailing, metrics: nil, views: ["v": v]))
self.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: verticalVisualFormat, options: .directionLeadingToTrailing, metrics: nil, views: ["v": v]))
}
}
}
}
}
Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.
There are a thousand and one ways to do it. Here's one using dc
(a reverse-polish desk calculator which supports unlimited precision arithmetic):
dc <<<"$num1 $num2 + p"
But if that's too bash-y for you (or portability matters) you could say
echo $num1 $num2 + p | dc
But maybe you're one of those people who thinks RPN is icky and weird; don't worry! bc
is here for you:
bc <<< "$num1 + $num2"
echo $num1 + $num2 | bc
That said, there are some unrelated improvements you could be making to your script:
#!/bin/bash
num=0
metab=0
for ((i=1; i<=2; i++)); do
for j in output-$i-* ; do # 'for' can glob directly, no need to ls
echo "$j"
# 'grep' can read files, no need to use 'cat'
metab=$(grep EndBuffer "$j" | awk '{sum+=$2} END { print sum/120}')
num=$(( $num + $metab ))
done
echo "$num"
done
As described in Bash FAQ 022, Bash does not natively support floating point numbers. If you need to sum floating point numbers the use of an external tool (like bc
or dc
) is required.
In this case the solution would be
num=$(dc <<<"$num $metab + p")
To add accumulate possibly-floating-point numbers into num
.
Example is here:
If you want to set the compatibility mode in the browser itself and not in the html do the following
As shown in the image below. The website should then open up with IE 10 Compatibility view.
Quite late to this party, today I had the same problem.
The right answer on macOs I think is use jenv
brew install jenv openjdk@11
jenv add /usr/local/opt/openjdk@11
And then add into Intellij IDEA as new SDK the following path:
~/.jenv/versions/11/libexec/openjdk.jdk/Contents/Home/
Yet another solution for random colors:
function colorize(str) {
for (var i = 0, hash = 0; i < str.length; hash = str.charCodeAt(i++) + ((hash << 5) - hash));
color = Math.floor(Math.abs((Math.sin(hash) * 10000) % 1 * 16777216)).toString(16);
return '#' + Array(6 - color.length + 1).join('0') + color;
}
It's a mixed of things that does the job for me. I used JFreeman Hash function (also an answer in this thread) and Asykäri pseudo random function from here and some padding and math from myself.
I doubt the function produces evenly distributed colors, though it looks nice and does that what it should do.
Applying the DRY principle to Omar's solution, here's an HTML Helper extension:
using System.Web.Mvc;
using System.Text.RegularExpressions;
namespace System.Web.Mvc.Html {
public static class MyHtmlHelpers {
public static MvcHtmlString EncodedReplace(this HtmlHelper helper, string input, string pattern, string replacement) {
return new MvcHtmlString(Regex.Replace(helper.Encode(input), pattern, replacement));
}
}
}
Usage (with improved regex):
@Html.EncodedReplace(Model.CommentText, "[\n\r]+", "<br />")
This also has the added benefit of putting less onus on the Razor View developer to ensure security from XSS vulnerabilities.
My concern with Jacob's solution is that rendering the line breaks with CSS breaks the HTML semantics.
Easiest and clearest way I'd say is:
var maxHeight = 0, maxHeightElement = null;
$('.panel').each(function(){
if ($(this).height() > maxHeight) {
maxHeight = $(this).height();
maxHeightElement = $(this);
}
});
In @ComponentScan("org.pharmacy")
, you are declaring org.pharmacy
package.
But your components in com.pharmacy
package.
I had the same issue. The other solutions here didn't work for me because I couldn't even see the Indigo / Helios update repos. The problem was that Eclipse was in Program Files, but I wasn't running it as an administrator.
just select '0' as the value for the desired column
I ran into this error message today and wanted to post the resolution to my particular my case. It turns out that my problem was that one of my css files was missing a closing brace and this was causing the file to not be compiled. It may be harder to notice this if you have an automated process that sets everything up (including the asset precompile) for your production environment.
You can use this code to get your desire output

Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.
Ran into this issue. I had to add the following to my build.grade:
apply plugin: 'kotlin-android'
I solve it by download the reportviewer.exe and install it. After the installation, all related assemblies will be available in C:\Windows\assembly\GAC_MSIL, then you can refer it in web config
Try this:
import shutil
import os
source_dir = '/path/to/source_folder'
target_dir = '/path/to/dest_folder'
file_names = os.listdir(source_dir)
for file_name in file_names:
shutil.move(os.path.join(source_dir, file_name), target_dir)
Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?
Use dynamic query as below:
String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;
If I want to simply run the above query and get a List what is the best way?
List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
public String mapRow(ResultSet rs, int rowNum)
throws SQLException {
return rs.getString(1);
}
});
EDIT: To Stop SQL Injection, check for non word characters in the colName as :
Pattern pattern = Pattern.compile("\\W");
if(pattern.matcher(str).find()){
//throw exception as invalid column name
}
I would do like below, where $products
is the actual array given in the problem at the very beginning.
print_r(
array_search("breville-variable-temperature-kettle-BKE820XL",
array_map(function($product){return $product["slug"];},$products))
);
(On windows) not sure why this was happening but I had my PYTHONPATH setup to point to c:\python27 where python was installed. in combination with virtualenv this produced the mentioned bug.
resolved by removing the PYTHONPATH env var all together
Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:
$.ajax({
type: "POST",
url: "index.php",
dataType: "json",
data: JSON.stringify({ paramName: info }),
success: function(msg){
$('.answer').html(msg);
}
});
You just need to make sure you include the JSON2.js file in your page...
Shouldn't you have:
DELETE FROM tableA WHERE entitynum IN (...your select...)
Now you just have a WHERE with no comparison:
DELETE FROM tableA WHERE (...your select...)
So your final query would look like this;
DELETE FROM tableA WHERE entitynum IN (
SELECT tableA.entitynum FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')
)
You can also integrate it with any 3rd-party libraries which makes use of JQuery.
One such library is Backbone, which is actually going to support Deferred in their next version.
It depends. You could
string.match(/^abc$/)
But that would not match the following string: 'the first 3 letters of the alphabet are abc. not abc123'
I think you would want to use \b
(word boundaries):
var str = 'the first 3 letters of the alphabet are abc. not abc123';_x000D_
var pat = /\b(abc)\b/g;_x000D_
console.log(str.match(pat));
_x000D_
Live example: http://jsfiddle.net/uu5VJ/
If the former solution works for you, I would advise against using it.
That means you may have something like the following:
var strs = ['abc', 'abc1', 'abc2']
for (var i = 0; i < strs.length; i++) {
if (strs[i] == 'abc') {
//do something
}
else {
//do something else
}
}
While you could use
if (str[i].match(/^abc$/g)) {
//do something
}
It would be considerably more resource-intensive. For me, a general rule of thumb is for a simple string comparison use a conditional expression, for a more dynamic pattern use a regular expression.

If abc
is an optional, then the usual way to do this would be to attempt to unwrap it in an if statement:
if let variableName = abc { // If casting, use, eg, if let var = abc as? NSString
// variableName will be abc, unwrapped
} else {
// abc is nil
}
However, to answer your actual question, your problem is that you're typing the variable such that it can never be optional.
Remember that in Swift, nil
is a value which can only apply to optionals.
Since you've declared your variable as:
var abc: NSString ...
it is not optional, and cannot be nil
.
Try declaring it as:
var abc: NSString? ...
or alternatively letting the compiler infer the type.
If you don't want to bother with weird expansions from bash you can do this
me$ FOO="BAR \x2A BAR" # 2A is hex code for *
me$ echo -e $FOO
BAR * BAR
me$
Explanation here why using -e option of echo makes life easier:
Relevant quote from man here:
SYNOPSIS
echo [SHORT-OPTION]... [STRING]...
echo LONG-OPTION
DESCRIPTION
Echo the STRING(s) to standard output.
-n do not output the trailing newline
-e enable interpretation of backslash escapes
-E disable interpretation of backslash escapes (default)
--help display this help and exit
--version
output version information and exit
If -e is in effect, the following sequences are recognized:
\\ backslash
...
\0NNN byte with octal value NNN (1 to 3 digits)
\xHH byte with hexadecimal value HH (1 to 2 digits)
For the hex code you can check man ascii page (first line in octal, second decimal, third hex):
051 41 29 ) 151 105 69 i
052 42 2A * 152 106 6A j
053 43 2B + 153 107 6B k

You may want to consider Tuples as they're similar to lists but can’t be modified. They take up slightly less memory and are faster to access. They aren’t as flexible but are more efficient than lists. Their normal use is to serve as dictionary keys.
Sets are also sequence structures but with two differences from lists and tuples. Although sets do have an order, that order is arbitrary and not under the programmer’s control. The second difference is that the elements in a set must be unique.
set
by definition. [python | wiki].
>>> x = set([1, 1, 2, 2, 3, 3])
>>> x
{1, 2, 3}
Put very simply, request timeout means there was no response whereas destination unreachable may mean the address specified does not exist i.e. you typed in the wrong IP address.
For a quick solution, you can use AtomicInteger or any of the atomic variables which will let you change the value inside the method using the inbuilt methods. Here is sample code:
import java.util.concurrent.atomic.AtomicInteger;
public class PrimitivePassByReferenceSample {
/**
* @param args
*/
public static void main(String[] args) {
AtomicInteger myNumber = new AtomicInteger(0);
System.out.println("MyNumber before method Call:" + myNumber.get());
PrimitivePassByReferenceSample temp = new PrimitivePassByReferenceSample() ;
temp.changeMyNumber(myNumber);
System.out.println("MyNumber After method Call:" + myNumber.get());
}
void changeMyNumber(AtomicInteger myNumber) {
myNumber.getAndSet(100);
}
}
Output:
MyNumber before method Call:0
MyNumber After method Call:100

I had the same issue and tried most of the solutions mentioned above and they did not fix it..
At then end, I went to my .csproj
file and viewed it in the text editor, I found that my xml file that I put in the /Drawable
was not set to be AndroidResouces
it was just of type Content
.
Changing that to be of type AndroidResouces
fixed the issue for me.
Just to complement @Marcus Ekwall 's answer. Doing like this will get only anchor links. And you aren't going to have problems if you have a mix of anchor links and regular ones.
jQuery(document).ready(function(jQuery) {
var topMenu = jQuery("#top-menu"),
offset = 40,
topMenuHeight = topMenu.outerHeight()+offset,
// All list items
menuItems = topMenu.find('a[href*="#"]'),
// Anchors corresponding to menu items
scrollItems = menuItems.map(function(){
var href = jQuery(this).attr("href"),
id = href.substring(href.indexOf('#')),
item = jQuery(id);
//console.log(item)
if (item.length) { return item; }
});
// so we can get a fancy scroll animation
menuItems.click(function(e){
var href = jQuery(this).attr("href"),
id = href.substring(href.indexOf('#'));
offsetTop = href === "#" ? 0 : jQuery(id).offset().top-topMenuHeight+1;
jQuery('html, body').stop().animate({
scrollTop: offsetTop
}, 300);
e.preventDefault();
});
// Bind to scroll
jQuery(window).scroll(function(){
// Get container scroll position
var fromTop = jQuery(this).scrollTop()+topMenuHeight;
// Get id of current scroll item
var cur = scrollItems.map(function(){
if (jQuery(this).offset().top < fromTop)
return this;
});
// Get the id of the current element
cur = cur[cur.length-1];
var id = cur && cur.length ? cur[0].id : "";
menuItems.parent().removeClass("active");
if(id){
menuItems.parent().end().filter("[href*='#"+id+"']").parent().addClass("active");
}
})
})
Basically i replaced
menuItems = topMenu.find("a"),
by
menuItems = topMenu.find('a[href*="#"]'),
To match all links with anchor somewhere, and changed all that what was necessary to make it work with this

I've found a solution for width: "100%", height: "auto" if you know the aspectRatio (width / height) of the image.
Here's the code:
import { Image, StyleSheet, View } from 'react-native';
const image = () => (
<View style={styles.imgContainer}>
<Image style={styles.image} source={require('assets/images/image.png')} />
</View>
);
const style = StyleSheet.create({
imgContainer: {
flexDirection: 'row'
},
image: {
resizeMode: 'contain',
flex: 1,
aspectRatio: 1 // Your aspect ratio
}
});
This is the most simplest way I could get it to work without using onLayout
or Dimension
calculations. You can even wrap it in a simple reusable component if needed. Give it a shot if anyone is looking for a simple implementation.

php artisan migrate:fresh
Should do the job, if you are in development and the desired outcome is to start all over.
In production, that maybe not the desired thing, so you should be adverted. (The migrate:fresh command will drop all tables from the database and then execute the migrate command).
Now we can do this with:
<style type="text/css" media="print">
@page {

margin: 0; /* this affects the margin in the printer settings */
}
</style>
Try this,

$arr2=array('result1'=>'hijk','result2'=>'lmn');
$arr3=array($arr1,$arr2);
print (json_encode($arr3));

EDIT: I've squeezed the filter a lot. I couldn't wrap my head around it before how to make sure something really fit within the time period. It's this: Start date BEFORE the END of the time period, and End date AFTER the BEGINNING of the time period
With the help of someone in my office I think we've figured out how to include everyone in the filter. There are 5 scenarios where a student would be deemed active during the time period in question:
1) Student started and ended during the time period.
2) Student started before and ended during the time period.
3) Student started before and ended after the time period.
4) Student started during the time period and ended after the time period.
5) Student started during the time period and is still active (Doesn't have an end date yet)
Given these criteria, we can actually condense the statements into a few groups because a student can only end between the period dates, after the period date, or they don't have an end date:
1) Student ends during the time period AND [Student starts before OR during]
2) Student ends after the time period AND [Student starts before OR during]
3) Student hasn't finished yet AND [Student starts before OR during]
(
(
student_programs.END_DATE >= '07/01/2017 00:0:0'
OR
student_programs.END_DATE Is Null
)
AND
student_programs.START_DATE <= '06/30/2018 23:59:59'
)
I think this finally covers all the bases and includes all scenarios where a student, or event, or anything is active during a time period when you only have start date and end date. Please, do not hesitate to tell me that I am missing something. I want this to be perfect so others can use this, as I don't believe the other answers have gotten everything right yet.
JavaScript is, with a very few exceptions (XMLHttpRequest
onreadystatechange
handlers in some versions of Firefox) event-loop concurrent. So you needn't worry about locking in this case.
JavaScript has a concurrency model based on an "event loop". This model is quite different than the model in other languages like C or Java.
...
A JavaScript runtime contains a message queue, which is a list of messages to be processed. To each message is associated a function. When the stack is empty, a message is taken out of the queue and processed. The processing consists of calling the associated function (and thus creating an initial stack frame) The message processing ends when the stack becomes empty again.
...
Each message is processed completely before any other message is processed. This offers some nice properties when reasoning about your program, including the fact that whenever a function runs, it cannot be pre-empted and will run entirely before any other code runs (and can modify data the function manipulates). This differs from C, for instance, where if a function runs in a thread, it can be stopped at any point to run some other code in another thread.
A downside of this model is that if a message takes too long to complete, the web application is unable to process user interactions like click or scroll. The browser mitigates this with the "a script is taking too long to run" dialog. A good practice to follow is to make message processing short and if possible cut down one message into several messages.

Error Code 9009 means error file not found. All the underlying reasons posted in the answers here are good inspiration to figure out why, but the error itself simply means a bad path.

SELECT INTO and SET Both works for some variables and not for others. Event syntaxes are the same
SET @Invoice_UserId := (SELECT UserId FROM invoice WHERE InvoiceId = @Invoice_Id LIMIT 1); -- Working
SET @myamount := (SELECT amount FROM invoice WHERE InvoiceId = @Invoice_Id LIMIT 1); - Not working
SELECT Amount INTO @myamount FROM invoice WHERE InvoiceId = 29 LIMIT 1; - Not working
If I run these queries directly then works, but not working in stored procedure.
You should use Java's built in serialization mechanism. To use it, you need to do the following:
Declare the Club
class as implementing Serializable
:
public class Club implements Serializable {
...
}
This tells the JVM that the class can be serialized to a stream. You don't have to implement any method, since this is a marker interface.
To write your list to a file do the following:
FileOutputStream fos = new FileOutputStream("t.tmp");
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(clubs);
oos.close();
To read the list from a file, do the following:
FileInputStream fis = new FileInputStream("t.tmp");
ObjectInputStream ois = new ObjectInputStream(fis);
List<Club> clubs = (List<Club>) ois.readObject();
ois.close();
You can use urllib2 to make the HTTP requests, and then you'll have web content.
You can get it like this:
import urllib2
response = urllib2.urlopen('http://example.com')
html = response.read()
Beautiful Soup is a python HTML parser that is supposed to be good for screen scraping.
In particular, here is their tutorial on parsing an HTML document.
Good luck!
This error occurs when you're trying to target an element that is wrapped in a condition.
So, here if I use ngIf in place of [hidden], it will give me TypeError: Cannot read property 'nativeElement' of undefined
So use [hidden], class.show or class.hide in place of *ngIf.
<button (click)="displayMap()" class="btn btn-primary">Display Map</button>
<div [hidden]="!display">
<div #mapContainer id="map">Content to render when condition is true.</div>

if it is a RSA key
openssl rsa -pubout -in my_rsa_key.pem
if you need it in a format for openssh , please see Use RSA private key to generate public key?
Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.
If you need to continuously insert an element at the beginning of an array, it is faster to use push
statements followed by a call to reverse
, instead of calling unshift
all the time.

Wrong syntax. Here you are:
insert into user_by_category (game_category,customer_id) VALUES ('Goku','12');
or:
insert into user_by_category ("game_category","customer_id") VALUES ('Kakarot','12');
The second one is normally used for case-sensitive column names.
Just to update this answer for the sake of others who happen to end up on this page.
In Rails 3, you just need to create a file at views/users/show.json.erb
. The @user
object will be available to the view (just like it would be for html.) You don't even need to_json
anymore.
To summarize, it's just
# users contoller
def show
@user = User.find( params[:id] )
respond_to do |format|
format.html
format.json
end
end
and
/* views/users/show.json.erb */
{
"name" : "<%= @user.name %>"
}
You can use below commands for the same.
show create table <table>;
desc formatted <table>;
describe formatted <table>;
You aren't actually sending JSON. You are passing an object as the data
, but you need to stringify the object and pass the string instead.
Your dataType: "json"
only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.
Change to:
$.ajax({
type: "POST",
url: hb_base_url + "consumer",
contentType: "application/json",
dataType: "json",
data: JSON.stringify({
first_name: $("#namec").val(),
last_name: $("#surnamec").val(),
email: $("#emailc").val(),
mobile: $("#numberc").val(),
password: $("#passwordc").val()
}),
success: function(response) {
console.log(response);
},
error: function(response) {
console.log(response);
}
});
Step 1: Install update http://httpjunkie.com/2013/340/develop-mvc-5-with-asp-net-identity-in-visual-studio-2012/.
OK, so that gets you to be able to start from a blank ASP.NET MVC project, but a lot of people want the FULL INTERNET APPLICATION as shipped with Visual Studio 2013.

Short answer:
int
uses up 4 bytes of memory (and it CANNOT contain a decimal), double
uses 8 bytes of memory. Just different tools for different purposes.
This is an old thread, but another solution, which I prefer, is just update the cityId and not assign the hole model City to Employee... to do that Employee should look like:
public class Employee{
...
public int? CityId; //The ? is for allow City nullable
public virtual City City;
}
Then it's enough assigning:
e1.CityId=city1.ID;
In order for sudo to work the way everyone suggest, you need to be in the admin

I would not use URLEncoder
. Besides being incorrectly named (URLEncoder
has nothing to do with URLs), inefficient (it uses a StringBuffer
instead of Builder and does a couple of other things that are slow) Its also way too easy to screw it up.
Instead I would use URIBuilder
or Spring's org.springframework.web.util.UriUtils.encodeQuery
or Commons Apache HttpClient
.
The reason being you have to escape the query parameters name (ie BalusC's answer q
) differently than the parameter value.
The only downside to the above (that I found out painfully) is that URL's are not a true subset of URI's.
Sample code:
import org.apache.http.client.utils.URIBuilder;
URIBuilder ub = new URIBuilder("http://example.com/query");
ub.addParameter("q", "random word £500 bank \$");
String url = ub.toString();
// Result: http://example.com/query?q=random+word+%C2%A3500+bank+%24

TL;DR version: remote-tracking branch origin/master
used to exist, but does not now, so local branch source
is tracking something that does not exist, which is suspicious at best—it means a different Git feature is unable to do anything for you—and Git is warning you about it. You have been getting along just fine without having the "upstream tracking" feature work as intended, so it's up to you whether to change anything.
For another take on upstream settings, see Why do I have to "git push --set-upstream origin <branch>"?
This warning is a new thing in Git, appearing first in Git 1.8.5. The release notes contain just one short bullet-item about it:
- "git branch -v -v" (and "git status") did not distinguish among a branch that is not based on any other branch, a branch that is in sync with its upstream branch, and a branch that is configured with an upstream branch that no longer exists.
To describe what it means, you first need to know about "remotes", "remote-tracking branches", and how Git handles "tracking an upstream". (Remote-tracking branches is a terribly flawed term—I've started using remote-tracking names instead, which I think is a slight improvement. Below, though, I'll use "remote-tracking branch" for consistency with Git documentation.)
Each "remote" is simply a name, like origin
or octopress
in this case. Their purpose is to record things like the full URL of the places from which you git fetch
or git pull
updates. When you use git fetch remote,
1 Git goes to that remote (using the saved URL) and brings over the appropriate set of updates. It also records the updates, using "remote-tracking branches".
A "remote-tracking branch" (or remote-tracking name) is simply a recording of a branch name as-last-seen on some "remote". Each remote is itself a Git repository, so it has branches. The branches on remote "origin" are recorded in your local repository under remotes/origin/
. The text you showed says that there's a branch named source
on origin
, and branches named 2.1
, linklog
, and so on on octopress
.
(A "normal" or "local" branch, of course, is just a branch-name that you have created in your own repository.)
Last, you can set up a (local) branch to "track" a "remote-tracking branch". Once local branch L
is set to track remote-tracking branch R
, Git will call R
its "upstream" and tell you whether you're "ahead" and/or "behind" the upstream (in terms of commits). It's normal (even recommend-able) for the local branch and remote-tracking branches to use the same name (except for the remote prefix part), like source
and origin/source
, but that's not actually necessary.
And in this case, that's not happening. You have a local branch source
tracking a remote-tracking branch origin/master
.
You're not supposed to need to know the exact mechanics of how Git sets up a local branch to track a remote one, but they are relevant below, so I'll show how this works. We start with your local branch name, source
. There are two configuration entries using this name, spelled branch.source.remote
and branch.source.merge
. From the output you showed, it's clear that these are both set, so that you'd see the following if you ran the given commands:
$ git config --get branch.source.remote
origin
$ git config --get branch.source.merge
refs/heads/master
Putting these together,2 this tells Git that your branch source
tracks your "remote-tracking branch", origin/master
.
But now look at the output of git branch -a
, which shows all the local and remote-tracking branch names in your repository. The remote-tracking names are listed under remotes/
... and there is no remotes/origin/master
. Presumably there was, at one time, but it's gone now.
Git is telling you that you can remove the tracking information with --unset-upstream
. This will clear out both branch.source.origin
and branch.source.merge
, and stop the warning.
It seems fairly likely that what you want, though, is to switch from tracking origin/master
, to tracking something else: probably origin/source
, but maybe one of the octopress/
names.
You can do this with git branch --set-upstream-to
,3 e.g.:
$ git branch --set-upstream-to=origin/source
(assuming you're still on branch "source", and that origin/source
is the upstream you want—there is no way for me to tell which one, if any, you actually want, though).
(See also How do you make an existing Git branch track a remote branch?)
I think the way you got here is that when you first did a git clone
, the thing you cloned-from had a branch master
. You also had a branch master
, which was set to track origin/master
(this is a normal, standard setup for git). This meant you had branch.master.remote
and branch.master.merge
set, to origin
and refs/heads/master
. But then your origin
remote changed its name from master
to source
. To match, I believe you also changed your local name from master
to source
. This changed the names of your settings, from branch.master.remote
to branch.source.remote
and from branch.master.merge
to branch.source.merge
... but it left the old values, so branch.source.merge
was now wrong.
It was at this point that the "upstream" linkage broke, but in Git versions older than 1.8.5, Git never noticed the broken setting. Now that you have 1.8.5, it's pointing this out.
That covers most of the questions, but not the "do I need to fix it" one. It's likely that you have been working around the broken-ness for years now, by doing git pull remote branch
(e.g., git pull origin source
). If you keep doing that, it will keep working around the problem—so, no, you don't need to fix it. If you like, you can use --unset-upstream
to remove the upstream and stop the complaints, and not have local branch source
marked as having any upstream at all.
The point of having an upstream is to make various operations more convenient. For instance, git fetch
followed by git merge
will generally "do the right thing" if the upstream is set correctly, and git status
after git fetch
will tell you whether your repo matches the upstream one, for that branch.
If you want the convenience, re-set the upstream.
1git pull
uses git fetch
, and as of Git 1.8.4, this (finally!) also updates the "remote-tracking branch" information. In older versions of Git, the updates did not get recorded in remote-tracking branches with git pull
, only with git fetch
. Since your Git must be at least version 1.8.5 this is not an issue for you.
2Well, this plus a configuration line I'm deliberately ignoring that is found under remote.origin.fetch
. Git has to map the "merge" name to figure out that the full local name for the remote-branch is refs/remotes/origin/master
. The mapping almost always works just like this, though, so it's predictable that master
goes to origin/master
.
3Or, with git config
. If you just want to set the upstream to origin/source
the only part that has to change is branch.source.merge
, and git config branch.source.merge refs/heads/source
would do it. But --set-upstream-to
says what you want done, rather than making you go do it yourself manually, so that's a "better way".

You can't; at least not the same way you can test whether a pointer is NULL
.
A std::string
object is always initialized and always contains a string; its contents by default are an empty string (""
).
You can test for emptiness (using s.size() == 0

After trying the 2 answers above (changing deployment target and restarting my iOS device), what finally fixed it for me was restarting my Mac.
Your code has two problems. One was identified and answered, but the other wasn't. The first was that your selector was missing the name of its parameter. However, even when you fix that, the line will still raise an exception, assuming your revised method signature still includes more than one argument. Let's say your revised method is declared as:
-(void)myTestWithString:(NSString *)sourceString comparedTo:(NSString *)testString ;
Creating selectors for methods that take multiple arguments is perfectly valid (e.g. @selector(myTestWithString:comparedTo:) ). However, the performSelector method only allows you to pass one value to myTest, which unfortunately has more than one parameter. It will error out and tell you that you didn't supply enough values.
You could always redefine your method to take a collection as it's only parameter:
-(void)myTestWithObjects:(NSDictionary *)testObjects ;
However, there is a more elegant solution (that doesn't require refactoring). The answer is to use NSInvocation, along with its setArgument:atIndex:
and invoke
methods.
I've written up an article, including a code example, if you want more details. The focus is on threading, but the basics still apply.
Good luck!
This worked for me.
I want to add somethings different from definitions of words. Most of them will be visual.
Technically, LDAP is just a protocol that defines the method by which directory data is accessed.Necessarily, it also defines and describes how data is represented in the directory service
Data is represented in an LDAP system as a hierarchy of objects, each of which is called an entry. The resulting tree structure is called a Directory Information Tree (DIT). The top of the tree is commonly called the root (a.k.a base or the suffix).
To navigate the DIT we can define a path (a DN) to the place where our data is (cn=DEV-India,ou=Distrubition Groups,dc=gp,dc=gl,dc=google,dc=com will take us to a unique entry) or we can define a path (a DN) to where we think our data is (say, ou=Distrubition Groups,dc=gp,dc=gl,dc=google,dc=com) then search for the attribute=value or multiple attribute=value pairs to find our target entry (or entries).

The Java Virtual Machine takes two command line arguments which set the initial and maximum heap sizes: -Xms and -Xmx. You can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there.
For example if you want a 512Mb initial and 1024Mb maximum heap size you could use:
under Windows:
SET _JAVA_OPTIONS = -Xms512m -Xmx1024m
under Linux:
export _JAVA_OPTIONS="-Xms512m -Xmx1024m"
It is possible to read the default JVM heap size programmatically by using totalMemory() method of Runtime class. Use following code to read JVM heap size.
public class GetHeapSize {
public static void main(String[]args){
//Get the jvm heap size.
long heapSize = Runtime.getRuntime().totalMemory();
//Print the jvm heap size.
System.out.println("Heap Size = " + heapSize);
}
}
Please note that the problem is not white
color. It is because it is being transparent.
When an element is made transparent, all of its child element's opacity; alpha filter in IE 6 7 etc, is changed to the new value.
So you cannot say that it is white!
You can place an element above it, and change that element's transparency to 1
while changing the image's transparency to .2
or what so ever you want to.

Sometimes your build folder simply needs cleaning - it certainly worked for me. Thanks to loafer-project for the solution.
use this
select * from xxx where dates between '10/oct/2012' and '10/dec/2012'
you are entering string, So give the name of month as according to format...
You could use an <a>
tag with different styles:
a:link { }
a:visited { }
a:hover { }
a:active { }
I'd recommend using that in conjunction with CSS sprites: https://css-tricks.com/css-sprites/
To clear from the current position to the end of the current line, do this:
public static void ClearToEndOfCurrentLine()
{
int currentLeft = Console.CursorLeft;
int currentTop = Console.CursorTop;
Console.Write(new String(' ', Console.WindowWidth - currentLeft));
Console.SetCursorPosition(currentLeft, currentTop);
}
I think you may have over-complicated your code: If you are just checking to see if a service is running and, if not, run it and then stop re-evaluating, the following should suffice:
$ServiceName = 'Serenade'
$arrService = Get-Service -Name $ServiceName
while ($arrService.Status -ne 'Running')
{
Start-Service $ServiceName
write-host $arrService.status
write-host 'Service starting'
Start-Sleep -seconds 60
$arrService.Refresh()
if ($arrService.Status -eq 'Running')
{
Write-Host 'Service is now Running'
}
}
Hyper Text Transfer Protocol (HTTP) is a protocol used for transferring web pages (like the one you're reading right now). A protocol is really nothing but a standard way of doing things. If you were to meet the President of the United States, or the king of a country, there would be specific procedures that you'd have to follow. You couldn't just walk up and say "hey dude". There would be a specific way to walk, to talk, a standard greeting, and a standard way to end the conversation. Protocols in the TCP/IP stack serve the same purpose.
The TCP/IP stack has four layers: Application, Transport, Internet, and Network. At each layer there are different protocols that are used to standardize the flow of information, and each one is a computer program (running on your computer) that's used to format the information into a packet as it's moving down the TCP/IP stack. A packet is a combination of the Application Layer data, the Transport Layer header (TCP or UDP), and the IP layer header (the Network Layer takes the packet and turns it into a frame).
...consists of all applications that use the network to transfer data. It does not care about how the data gets between two points and it knows very little about the status of the network. Applications pass data to the next layer in the TCP/IP stack and then continue to perform other functions until a reply is received. The Application Layer uses host names (like www.dalantech.com) for addressing. Examples of application layer protocols: Hyper Text Transfer Protocol (HTTP -web browsing), Simple Mail Transfer Protocol (SMTP -electronic mail), Domain Name Services (DNS -resolving a host name to an IP address), to name just a few.
The main purpose of the Application Layer is to provide a common command language and syntax between applications that are running on different operating systems -kind of like an interpreter. The data that is sent by an application that uses the network is formatted to conform to one of several set standards. The receiving computer can understand the data that is being sent even if it is running a different operating system than the sender due to the standards that all network applications conform to.
...is responsible for assigning source and destination port numbers to applications. Port numbers are used by the Transport Layer for addressing and they range from 1 to 65,535. Port numbers from 0 to 1023 are called "well known ports". The numbers below 256 are reserved for public (standard) services that run at the Application Layer. Here are a few: 25 for SMTP, 53 for DNS (udp for domain resolution and tcp for zone transfers) , and 80 for HTTP. The port numbers from 256 to 1023 are assigned by the IANA to companies for the applications that they sell.
Port numbers from 1024 to 65,535 are used for client side applications -the web browser you are using to read this page, for example. Windows will only assign port numbers up to 5000 -more than enough port numbers for a Windows based PC. Each application has a unique port number assigned to it by the transport layer so that as data is received by the Transport Layer it knows which application to give the data to. An example is when you have more than one browser window running. Each window is a separate instance of the program that you use to surf the web, and each one has a different port number assigned to it so you can go to www.dalantech.com in one browser window and this site does not load into another browser window. Applications like FireFox that use tabbed windows simply have a unique port number assigned to each tab
...is the "glue" that holds networking together. It permits the sending, receiving, and routing of data.
...consists of your Network Interface Card (NIC) and the cable connected to it. It is the physical medium that is used to transmit and receive data. The Network Layer uses Media Access Control (MAC) addresses, discussed earlier, for addressing. The MAC address is fixed at the time an interface was manufactured and cannot be changed. There are a few exceptions, like DSL routers that allow you to clone the MAC address of the NIC in your PC.

You may use:
if ( frm.product.value=="F" ){
var $select_box = $('[name=val]');
$select_box.find('[value=A],[value=C]').remove();
}
Update: If you modify your select box a bit to this
<select name="val" size="1" >
<option id="A" value="A">Apple</option>
<option id="C" value="C">Cars</option>
<option id="H" value="H">Honda</option>
<option id="F" value="F">Fiat</option>
<option id="I" value="I">Indigo</option>
</select>
the non-jQuery solution would be this
if ( frm.product.value=="F" ){
var elem = document.getElementById('A');
elem.parentNode.removeChild(elem);
var elem = document.getElementById('C');
elem.parentNode.removeChild(elem);
}
A two value assignment can be used for this purpose. Please check my sample program below
package main
import (
"fmt"
)
func main() {
//creating a map with 3 key-value pairs
sampleMap := map[string]int{"key1": 100, "key2": 500, "key3": 999}
//A two value assignment can be used to check existence of a key.
value, isKeyPresent := sampleMap["key2"]
//isKeyPresent will be true if key present in sampleMap
if isKeyPresent {
//key exist
fmt.Println("key present, value = ", value)
} else {
//key does not exist
fmt.Println("key does not exist")
}
}
It seems that your configuration is using the print
option for numpy.seterr
:
>>> import numpy as np
>>> np.array([1])/0 #'warn' mode
__main__:1: RuntimeWarning: divide by zero encountered in divide
array([0])
>>> np.seterr(all='print')
{'over': 'warn', 'divide': 'warn', 'invalid': 'warn', 'under': 'ignore'}
>>> np.array([1])/0 #'print' mode
Warning: divide by zero encountered in divide
array([0])
This means that the warning you see is not a real warning, but it's just some characters printed to stdout
(see the documentation for seterr
). If you want to catch it you can:
numpy.seterr(all='raise')
which will directly raise the exception. This however changes the behaviour of all the operations, so it's a pretty big change in behaviour.numpy.seterr(all='warn')
, which will transform the printed warning in a real warning and you'll be able to use the above solution to localize this change in behaviour.Once you actually have a warning, you can use the warnings
module to control how the warnings should be treated:
>>> import warnings
>>>
>>> warnings.filterwarnings('error')
>>>
>>> try:
... warnings.warn(Warning())
... except Warning:
... print 'Warning was raised as an exception!'
...
Warning was raised as an exception!
Read carefully the documentation for filterwarnings
since it allows you to filter only the warning you want and has other options. I'd also consider looking at catch_warnings
which is a context manager which automatically resets the original filterwarnings
function:
>>> import warnings
>>> with warnings.catch_warnings():
... warnings.filterwarnings('error')
... try:
... warnings.warn(Warning())
... except Warning: print 'Raised!'
...
Raised!
>>> try:
... warnings.warn(Warning())
... except Warning: print 'Not raised!'
...

Found this useful explanation from http://ng-learn.org/2013/11/Bower-vs-npm/
On one hand npm was created to install modules used in a node.js environment, or development tools built using node.js such Karma, lint, minifiers and so on. npm can install modules locally in a project ( by default in node_modules ) or globally to be used by multiple projects. In large projects the way to specify dependencies is by creating a file called package.json which contains a list of dependencies. That list is recognized by npm when you run npm install, which then downloads and installs them for you.
On the other hand bower was created to manage your frontend dependencies. Libraries like jQuery, AngularJS, underscore, etc. Similar to npm it has a file in which you can specify a list of dependencies called bower.json. In this case your frontend dependencies are installed by running bower install which by default installs them in a folder called bower_components.
As you can see, although they perform a similar task they are targeted to a very different set of libraries.
There is a class, Class
, that can do this:
Class c = Class.forName("MyClass"); // if you want to specify a class
Class c = this.getClass(); // if you want to use the current class
System.out.println("Package: "+c.getPackage()+"\nClass: "+c.getSimpleName()+"\nFull Identifier: "+c.getName());
If c
represented the class MyClass
in the package mypackage
, the above code would print:
Package: mypackage
Class: MyClass
Full Identifier: mypackage.MyClass
You can take this information and modify it for whatever you need, or go check the API for more information.
auto
is not a valid value for padding
property, the only thing you can do is take out padding: 0;
from the *
declaration, else simply assign padding
to respective property block.
If you remove padding: 0;
from * {}
than browser will apply default styles to your elements which will give you unexpected cross browser positioning offsets by few pixels, so it is better to assign padding: 0;
using *
and than if you want to override the padding, simply use another rule like
.container p {
padding: 5px;
}
Put the identity
element before the authentication
element
Just a supplement of the answers:
There may be a time you set all things right, but you may accidentally add some other UIs in you .xib
, like a UIButton
:
Just delete the extra UI, it works.
Okay, so..
// As you already stated, you know that a boolean defaults to false.
boolean turnedOn;
if(turnedOn) // Here, you are saying "if turnedOn (is true, that's implicit)
{
//then do this
}
else // if it is NOT true (it is false)
{
//do this
}
Does it make more sense now?
The if
statement will evaluate whatever code you put in it that returns a boolean value, and if the evaluation returns true, you enter the first block. Else (if the value is not true, it will be false, because a boolean can either be true or false) it will enter the - yep, you guessed it - the else {}
block.
A more verbose example.
If I am asked "are you hungry?", the simple answer is yes (true). or no (false).
boolean isHungry = true; // I am always hungry dammit.
if(isHungry) { // Yes, I am hungry.
// Well, you should go grab a bite to eat then!
} else { // No, not really.
// Ah, good for you. More food for me!
// As if this would ever happen - bad example, sorry. ;)
}
If you use this:
contentType: "application/json"
AJAX won't sent GET or POST params to the server.... dont know why.
It took me hours to lear it today.
Just Use:
$.ajax(
{ url : 'http://blabla.com/wsGetReport.php',
data : myFormData, type : 'POST', dataType : 'json',
// contentType: "application/json",
success : function(wsQuery) { }
}
)
Don't know why @Janos deleted his answer, but it's correct: your data frame Train
doesn't have a column named pre
. When you pass a formula and a data frame to a model-fitting function, the names in the formula have to refer to columns in the data frame. Your Train
has columns called residual.sugar
, total.sulfur
, alcohol
and quality
. You need to change either your formula or your data frame so they're consistent with each other.
And just to clarify: Pre
is an object containing a formula. That formula contains a reference to the variable pre
. It's the latter that has to be consistent with the data frame.
Another way (although it is a longer code) but it is faster than the above codes. Check it using %timeit function:
df[df.index.isin([1,3])]
PS: You figure out the reason
Looking at the Eclipse plugin docs I found some useful tasks that rebuilt my classpath and updated the required dependencies.
gradle cleanEclipse
to clean the Eclipse configuration completely. If this doesn;t work you may try more specific tasks:
gradle cleanEclipseProject
to remove the .project filegradle cleanEclipseClasspath
to empty the project's classpathgradle eclipse
to rebuild the Eclipse configurationI'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.
I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:
...
var signature = Get(url); // base64_encoded signature received from server
var inputtext= "inputtext"; // this is main text signature was created for
bool result = VerifySignature(inputtext, signature);
...
private bool VerifySignature(string input, string signature)
{
var result = false;
using (var cps=new RSACryptoServiceProvider())
{
// converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
byte[] signatureBytes = Convert.FromBase64String(signature);
cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes );
}
return result;
}
You cannot use both statements; the datetime
module contains a datetime
type. The local name datetime
in your own module can only refer to one or the other.
Use only import datetime
, then make sure that you always use datetime.datetime
to refer to the contained type:
import datetime
today_date = datetime.date.today()
date_time = datetime.datetime.strptime(date_time_string, '%Y-%m-%d %H:%M')
Now datetime
is the module, and you refer to the contained types via that.
Alternatively, import all types you need from the module:
from datetime import date, datetime
today_date = date.today()
date_time = datetime.strptime(date_time_string, '%Y-%m-%d %H:%M')
Here datetime
is the type from the module. date
is another type, from the same module.
If you're getting source in Content Use the following method
try

var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);
foreach (EmpModel item in data)
{
listPassingData?.Add(item);
}
}
catch (Exception ex)
{
Console.WriteLine($"Data get mathod problem {ex} ");
}
I suggest to use "return false" instead of useing some javascript in the href-tag:

<a href="#" onclick="document.getElementById('myform').submit(); return false;">send form</a>
int64_t

With the recent release of bootstrap 3, and the glyphicons being merged back to the main Bootstrap repo, Bootstrap CDN is now serving the complete Bootstrap 3.0 css including Glyphicons. The Bootstrap css reference is all you need to include: Glyphicons and its dependencies are on relative paths on the CDN site and are referenced in bootstrap.min.css
.
In html:
<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet">
In css:
@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css");
Here is a working demo.
Note that you have to use .glyphicon
classes instead of .icon
:
Example:
<span class="glyphicon glyphicon-heart"></span>
Also note that you would still need to include bootstrap.min.js
for usage of Bootstrap JavaScript components, see Bootstrap CDN for url.
If you want to use the Glyphicons separately, you can do that by directly referencing the Glyphicons css on Bootstrap CDN.
In html:
<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">
In css:
@import url("//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css");
Since the css
file already includes all the needed Glyphicons dependencies (which are in a relative path on the Bootstrap CDN site), adding the css
file is all there is to do to start using Glyphicons.
Here is a working demo of the Glyphicons without Bootstrap.

The idea behind Dijkstra's Algorithm is to explore all the nodes of the graph in an ordered way. The algorithm stores a priority queue where the nodes are ordered according to the cost from the start, and in each iteration of the algorithm the following operations are performed:
It's true that the algorithm calculates the cost of the path between the start (A in your case) and all the rest of the nodes, but you can stop the exploration of the algorithm when it reaches the goal (Z in your example). At this point you know the cost between A and Z, and the path connecting them.
I recommend you to use a library which implements this algorithm instead of coding your own. In Java, you might take a look to the Hipster library, which has a very friendly way to generate the graph and start using the search algorithms.
Here you have an example of how to define the graph and start using Dijstra with Hipster.
// Create a simple weighted directed graph with Hipster where
// vertices are Strings and edge values are just doubles
HipsterDirectedGraph<String,Double> graph = GraphBuilder.create()
.connect("A").to("B").withEdge(4d)
.connect("A").to("C").withEdge(2d)
.connect("B").to("C").withEdge(5d)
.connect("B").to("D").withEdge(10d)
.connect("C").to("E").withEdge(3d)
.connect("D").to("F").withEdge(11d)
.connect("E").to("D").withEdge(4d)
.buildDirectedGraph();
// Create the search problem. For graph problems, just use
// the GraphSearchProblem util class to generate the problem with ease.
SearchProblem p = GraphSearchProblem
.startingFrom("A")
.in(graph)
.takeCostsFromEdges()
.build();
// Search the shortest path from "A" to "F"
System.out.println(Hipster.createDijkstra(p).search("F"));
You only have to substitute the definition of the graph for your own, and then instantiate the algorithm as in the example.
I hope this helps!
The NuGet documentation provides instructions on how to accomplish this and I just followed them successfully for Visual Studio 2015 & Visual Studio 2017 against VSTS (Azure-hosted TFS). Everything is fully updated as of Nov 2016 Aug 2018.
I recommend you follow NuGet's instructions but just to recap what I did:
packages
folder is not committed to TFS. If it is, get it out of there..sln
file exists in unless otherwise specified (NuGet's instructions aren't completely clear on this)..nuget
folder. You can use Windows Explorer to name it .nuget.
for it to successfully save as .nuget
(it automatically removes the last period) but directly trying to name it .nuget
may not work (you may get an error or it may change the name, depending on your version of Windows).
Or name the directory nuget, and open the parent directory in command line prompt. type. ren nuget .nugetNuGet.config
file and add the following contents and save it:NuGet.config:
<?xml version="1.0" encoding="utf-8"?>

<add key="disableSourceControlIntegration" value="true" />
</solution>
</configuration>
.sln
's folder and create a new text file and name it .tfignore
(if using Windows Explorer, use the same trick as above and name it .tfignore.
).tfignore:
# Ignore the NuGet packages folder in the root of the repository.
# If needed, prefix 'packages' with additional folder names if it's
# not in the same folder as .tfignore.
packages

file and .nuget
folder to all of my various solutions and committed them and I no longer have the packages
folder trying to sneak into my source control repo!While not mine, I have found this .tfignore
template by sirkirby to be handy. The example in my answer covers the Nuget packages
folder but this template includes some other things as well as provides additional examples that can be useful if you wish to customize this further.

It worked well for me. Just one line code in cmd.
First, confirm that you have installed the gcc (for c) or g++ (for c++) compiler.
In cmd for gcc type:
gcc --version
in cmd for g++ type:
g++ --version
If it is installed then proceed.
Now, compile your .c or .cpp using cmd
for .c syntax:
gcc -o exe_filename yourfilename.c
Example:
gcc -o myfile myfile.c
Here exe_filename (myfile in example) is the name of your .exe file which you want to produce after compilation (Note: i have not put any extension here). And yourfilename.c (myfile.c in example) is the your source file which has the .c extension.
Now go to folder containing your .c file, here you will find a file with .exe extension. Just open it. Hurray..
For .cpp syntax:
g++ -o exe_filename yourfilename.cpp
After it the process is same as for .c .
Another approach starting from 0
and returning a String
public static String getCharForNumber(int i) {
return i < 0 || i > 25 ? "?" : String.valueOf((char) ('A' + i));
}
You might need to uninstall antivirus (in my case I had to get rid of Avast).
This makes sure that crypto::cng

After removing Avast:

Windows Defender is another program blocking the program to work, so you will need also to disable it for the time of using program at least.
I just encountered the same issue, my system is Win7. just use the command on terminal like: netstat -na|findstr port, you will see the port has been used. So if you want to start the server without this message, you can change other port that not been used.
I wrote a set extension methods a while back that work for several different kinds of Enum
s. One in particular works for what you are trying to accomplish and handles Enum
s with the FlagsAttribute
as well as Enum
s with different underlying types.
public static tEnum SetFlags<tEnum>(this Enum e, tEnum flags, bool set, bool typeCheck = true) where tEnum : IComparable
{
if (typeCheck)
{
if (e.GetType() != flags.GetType())
throw new ArgumentException("Argument is not the same type as this instance.", "flags");
}
var flagsUnderlyingType = Enum.GetUnderlyingType(typeof(tEnum));
var firstNum = Convert.ToUInt32(e);
var secondNum = Convert.ToUInt32(flags);
if (set)
firstNum |= secondNum;
else
firstNum &= ~secondNum;
var newValue = (tEnum)Convert.ChangeType(firstNum, flagsUnderlyingType);
if (!typeCheck)
{
var values = Enum.GetValues(typeof(tEnum));
var lastValue = (tEnum)values.GetValue(values.Length - 1);
if (newValue.CompareTo(lastValue) > 0)
return lastValue;
}
return newValue;
}
From there you can add other more specific extension methods.
public static tEnum AddFlags<tEnum>(this Enum e, tEnum flags) where tEnum : IComparable
{
SetFlags(e, flags, true);
}
public static tEnum RemoveFlags<tEnum>(this Enum e, tEnum flags) where tEnum : IComparable
{
SetFlags(e, flags, false);
}
This one will change types of Enum
s like you are trying to do.
public static tEnum ChangeType<tEnum>(this Enum e) where tEnum : IComparable
{
return SetFlags(e, default(tEnum), true, false);
}
Be warned, though, that you CAN convert between any Enum
and any other Enum
using this method, even those that do not have flags. For example:
public enum Turtle
{
None = 0,
Pink,
Green,
Blue,
Black,
Yellow
}
[Flags]
public enum WriteAccess : short
{
None = 0,
Read = 1,
Write = 2,
ReadWrite = 3
}
static void Main(string[] args)
{
WriteAccess access = WriteAccess.ReadWrite;
Turtle turtle = access.ChangeType<Turtle>();
}
The variable turtle
will have a value of Turtle.Blue
.
However, there is safety from undefined Enum
values using this method. For instance:
static void Main(string[] args)
{
Turtle turtle = Turtle.Yellow;
WriteAccess access = turtle.ChangeType<WriteAccess>();
}
In this case, access
will be set to WriteAccess.ReadWrite
, since the WriteAccess
Enum
has a maximum value of 3.
Another side effect of mixing Enum
s with the FlagsAttribute
and those without it is that the conversion process will not result in a 1 to 1 match between their values.
public enum Letters
{
None = 0,
A,
B,
C,
D,
E,
F,
G,
H
}
[Flags]
public enum Flavors
{
None = 0,
Cherry = 1,
Grape = 2,
Orange = 4,
Peach = 8
}
static void Main(string[] args)
{
Flavors flavors = Flavors.Peach;
Letters letters = flavors.ChangeType<Letters>();
}
In this case, letters
will have a value of Letters.H
instead of Letters.D
, since the backing value of Flavors.Peach
is 8. Also, a conversion from Flavors.Cherry | Flavors.Grape
to Letters
would yield Letters.C
, which can seem unintuitive.
I was struggling with this too, so if you are presenting a FULLSCREEN modal view controller, make sure to set .modalPresentationStyle
as .fullscreen
and then, on your presenting view controller, just override .preferredStatusBarStyle
to .lightContent
.
So:
let navigationController = UINavigationController(rootViewController: viewController)
navigationController.modalPresentationStyle = .fullScreen // <=== make sure to set navigation modal presentation style
present(navigationController, animated: true, completion: nil)
on your custom view controller, override status bar style:
override var preferredStatusBarStyle: UIStatusBarStyle {
.lightContent
}
Alternative (Insert tooltip to user):

border-radius: 6px;
}
a.tooltips span:after {
content: '';
position: absolute;
top: 100%;

margin-left: -8px;
width: 0;
height: 0;
border-top: 8px solid #000000;
border-right: 8px solid transparent;

UEFA or FIFA don't seem to provide any API to get the information you want. However, there are some third-party services which support that:
OPTA - Both commercial and free. They have incredible database about matches. Whoscored.com currently uses it.
Others: livescoreboards, xmlsoccer, ...
I am using version 4.0.6 ( the current release) on Linux Mint. You need to install Mongodb Compass(mongodb GUI) to interact with your databases. Here is the link: https://docs.mongodb.com/compass/master/install/

The Array prototype's reverse method modifies the array and returns a reference to it, which means you can do this:
var sortedAsc = _.sortBy(collection, 'propertyName');
var sortedDesc = _.sortBy(collection, 'propertyName').reverse();
Also, the underscore documentation reads:
In addition, the Array prototype's methods are proxied through the chained Underscore object, so you can slip a
reverse
or apush
into your chain, and continue to modify the array.
which means you can also use .reverse()
while chaining:
var sortedDescAndFiltered = _.chain(collection)
.sortBy('propertyName')
.reverse()
.filter(_.property('isGood'))
.value();
Hello @sahil I update your answer for swift 3
let imageDataDict:[String: UIImage] = ["image": image]

NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict)
// `default` is now a property, not a method call
// Register to receive notification in your class
NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)
// handle notification
func showSpinningWheel(_ notification: NSNotification) {
print(notification.userInfo ?? "")
if let dict = notification.userInfo as NSDictionary? {
if let id = dict["image"] as? UIImage{
// do something with your image

}
}
Hope it's helpful. Thanks
The problem, as stated in your logs, is 2 dependencies trying to use different versions of 3rd dependency. Add one of the following to the app-gradle file:
androidTestCompile 'com.google.code.findbugs:jsr305:2.0.1'
androidTestCompile 'com.google.code.findbugs:jsr305:1.3.9'
You can use find
with the -prune
option.
An example from man find
:
cd /source-dir find . -name .snapshot -prune -o \( \! -name *~ -print0 \)| cpio -pmd0 /dest-dir This command copies the contents of /source-dir to /dest-dir, but omits files and directories named .snapshot (and anything in them). It also omits files or directories whose name ends in ~, but not their con- tents. The construct -prune -o \( ... -print0 \) is quite common. The idea here is that the expression before -prune matches things which are to be pruned. However, the -prune action itself returns true, so the following -o ensures that the right hand side is evaluated only for those directories which didn't get pruned (the contents of the pruned directories are not even visited, so their contents are irrelevant). The expression on the right hand side of the -o is in parentheses only for clarity. It emphasises that the -print0 action takes place only for things that didn't have -prune applied to them. Because the default `and' condition between tests binds more tightly than -o, this is the default anyway, but the parentheses help to show what is going on.
It is very complex to invoke Win32 from C#.
You should use the tool Handle.exe.
After that your C# code have to be the following:
string fileName = @"c:\aaa.doc";//Path to locked file
Process tool = new Process();
tool.StartInfo.FileName = "handle.exe";
tool.StartInfo.Arguments = fileName+" /accepteula";
tool.StartInfo.UseShellExecute = false;
tool.StartInfo.RedirectStandardOutput = true;
tool.Start();
tool.WaitForExit();
string outputTool = tool.StandardOutput.ReadToEnd();
string matchPattern = @"(?<=\s+pid:\s+)\b(\d+)\b(?=\s+)";
foreach(Match match in Regex.Matches(outputTool, matchPattern))
{
Process.GetProcessById(int.Parse(match.Value)).Kill();
}

With older Linux distros yet another option is to use wrapping script, e.g. in Perl or Python.
See solutions here:
http://linuxaria.com/article/how-to-make-dmesg-timestamp-human-readable?lang=en http://jmorano.moretrix.com/2012/03/dmesg-human-readable-timestamps/
On a system where sed
does not have the ability to edit files in place, I think the better solution would be to use perl
:
perl -pi -e 's/foo/bar/g' file.txt
Although this does create a temporary file, it replaces the original because an empty in place suffix/extension has been supplied.
What about something like this?
verpatch /va foodll.dll %VERSION% %FILEDESCR% %COMPINFO% %PRODINFO% %BUILDINFO%

To display a phone number with (###) ###-#### format, you can create a new HtmlHelper.

{
if (phone == null)
{
return new HtmlString(string.Empty);

if (phone.Length == 10)
{
formatted = $"({phone.Substring(0,3)}) {phone.Substring(3,3)}-{phone.Substring(6,4)}";
}
else if (phone.Length == 7)
{
formatted = $"{phone.Substring(0,3)}-{phone.Substring(3,4)}";
}
string s = $"<a href='tel:{phone}'>{formatted}</a>";
return new HtmlString(s);

What you want to do is put the console into "raw" mode (line editing bypassed and no enter key required) as opposed to "cooked" mode (line editing with enter key required.) On UNIX systems, the 'stty' command can change modes.
Now, with respect to Java... see Non blocking console input in Python and Java. Excerpt:
If your program must be console based, you have to switch your terminal out of line mode into character mode, and remember to restore it before your program quits. There is no portable way to do this across operating systems.
One of the suggestions is to use JNI. Again, that's not very portable. Another suggestion at the end of the thread, and in common with the post above, is to look at using jCurses.
You can use iconSize
like this:
floatingActionButton: FloatingActionButton(
onPressed: () {
// Add your onPressed code here
},
child: IconButton(
icon: isPlaying
? Icon(
Icons.pause_circle_outline,
)
: Icon(
Icons.play_circle_outline,
),
iconSize: 40,
onPressed: () {
setState(() {
isPlaying = !isPlaying;
});
},
),
),

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.
Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.
datetime.datetime.strptime
has problems with timezone parsing. Have a look at the dateutil

datetime.datetime(2012, 5, 8, 15, 14, 45, tzinfo=tzoffset(None, 28800))
I was having the same issue and the "make occurrences" and "annotations" solutions above did not help. If you are using Maven, I had to convert the project to a Maven project (right click on it in the Package Explorer and go down to configure), then build the project. Then the syntax coloring and highlighting worked correctly.
This will retrun you distinct Ids
var distinctIds = datatable.AsEnumerable()
.Select(s=> new {
id = s.Field<string>("id"),
})
.Distinct().ToList();
About the Count() method, if the IEnumarable is an ICollection, then we can't iterate across all items because we can retrieve the Count field of ICollection, if the IEnumerable is not an ICollection we must iterate across all items using a while with a MoveNext, take a look the .NET Framework Code:
public static int Count<TSource>(this IEnumerable<TSource> source)
{
if (source == null)
throw Error.ArgumentNull("source");
ICollection<TSource> collectionoft = source as ICollection<TSource>;
if (collectionoft != null)
return collectionoft.Count;
ICollection collection = source as ICollection;
if (collection != null)
return collection.Count;
int count = 0;
using (IEnumerator<TSource> e = source.GetEnumerator())
{
checked
{
while (e.MoveNext()) count++;
}
}
return count;
}

By default, when you fetch your URL, React native sets the cookie.
To see cookies and make sure that you can use the https://www.npmjs.com/package/react-native-cookie package. I used to be very satisfied with it.
Of course, Fetch does this when it does
credentials: "include",// or "some-origin"
Well, but how to use it
--- after installation this package ----
to get cookies:
import Cookie from 'react-native-cookie';
Cookie.get('url').then((cookie) => {
console.log(cookie);
});
to set cookies:
Cookie.set('url', 'name of cookies', 'value of cookies');
only this
But if you want a few, you can do it
1- as nested:
Cookie.set('url', 'name of cookies 1', 'value of cookies 1')
.then(() => {
Cookie.set('url', 'name of cookies 2', 'value of cookies 2')
.then(() => {
...
})
})
2- as back together
Cookie.set('url', 'name of cookies 1', 'value of cookies 1');
Cookie.set('url', 'name of cookies 2', 'value of cookies 2');
Cookie.set('url', 'name of cookies 3', 'value of cookies 3');
....
Now, if you want to make sure the cookies are set up, you can get it again to make sure.
Cookie.get('url').then((cookie) => {
console.log(cookie);
});
find . -type d > list.txt
Will list all directories and subdirectories under the current path. If you want to list all of the directories under a path other than the current one, change the .
to that other path.
If you want to exclude certain directories, you can filter them out with a negative condition:
find . -type d ! -name "~snapshot" > list.txt
Besides using multiple proxies or proxy-networks, you might want to try the planet-lab. (And probably there are other similar institutions around).
The social solution would be to post a question on some board that you are searching for volunteers that proxy your requests. (They only have to allow for one destination in their proxy config thus the danger of becoming spam-whores is relatively low.) You should prepare credentials that ensure your partners of the authenticity of the claim that the destination is indeed your computer.
Java does not truely support multidimensional arrays. In Java, a two-dimensional array is simply an array of arrays, a three-dimensional array is an array of arrays of arrays, a four-dimensional array is an array of arrays of arrays of arrays, and so on...
We can define a two-dimensional array as:
int[ ] num[ ] = {{1,2}, {1,2}, {1,2}, {1,2}}
int[ ][ ] num = new int[4][2]
num[0][0] = 1;
num[0][1] = 2;
num[1][0] = 1;
num[1][1] = 2;
num[2][0] = 1;
num[2][1] = 2;
num[3][0] = 1;
num[3][1] = 2;
If you don't allocate, let's say num[2][1]
, it is not initialized and then it is automatically allocated 0, that is, automatically num[2][1] = 0
;
Below, num1.length
gives you rows.
While num1[0].length
gives you the number of elements related to num1[0]
. Here num1[0]
has related arrays num1[0][0]
and num[0][1]
only.
Here we used a for
loop which helps us to calculate num1[i].length
. Here i
is incremented through a loop.
class array
{
static int[][] add(int[][] num1,int[][] num2)
{
int[][] temp = new int[num1.length][num1[0].length];
for(int i = 0; i<temp.length; i++)
{
for(int j = 0; j<temp[i].length; j++)
{
temp[i][j] = num1[i][j]+num2[i][j];
}
}
return temp;
}
public static void main(String args[])
{
/* We can define a two-dimensional array as
1. int[] num[] = {{1,2},{1,2},{1,2},{1,2}}
2. int[][] num = new int[4][2]

num[0][1] = 2;
num[1][0] = 1;
num[1][1] = 2;
num[2][0] = 1;
num[2][1] = 2;
num[3][0] = 1;
num[3][1] = 2;
If you don't allocate let's say num[2][1] is
not initialized, and then it is automatically
allocated 0, that is, automatically num[2][1] = 0;
3. Below num1.length gives you rows
4. While num1[0].length gives you number of elements
related to num1[0]. Here num1[0] has related arrays
num1[0][0] and num[0][1] only.
5. Here we used a 'for' loop which helps us to calculate
num1[i].length, and here i is incremented through a loop.
*/
int num1[][] = {{1,2},{1,2},{1,2},{1,2}};
int num2[][] = {{1,2},{1,2},{1,2},{1,2}};
int num3[][] = add(num1,num2);
for(int i = 0; i<num1.length; i++)
{
for(int j = 0; j<num1[j].length; j++)
System.out.println("num3[" + i + "][" + j + "]=" + num3[i][j]);
}
}
}
Hello there: If you need more control on where the link should redirect to, you could use this solution.
Ie. If the user is clicking in the CHECKOUT link, but you want to send him/her to checkout page if its registered(logged in) or registration page if he/she isn't.
You could use JSTL core LIKE:
<!--include the library-->
<%@ taglib prefix="core" uri="http://java.sun.com/jsp/jstl/core" %>
<%--create a var to store link--%>
<core:set var="linkToRedirect">
<%--test the condition you need--%>
<core:choose>
<core:when test="${USER IS REGISTER}">
checkout.jsp
</core:when>
<core:otherwise>
registration.jsp
</core:otherwise>
</core:choose>
</core:set>
EXPLAINING: is the same as...
//pseudo code
if(condition == true)
set linkToRedirect = checkout.jsp
else
set linkToRedirect = registration.jsp
THEN: in simple HTML...
<a href="your.domain.com/${linkToRedirect}">CHECKOUT</a>
All of the above are correct, but try this straight one-liner:
{{session()->has('message') ? session()->get('message') : ''}}
Add to manifest file the line:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
It fixed it for me.
